MACHINE FOR WINDING IAPER TUBES.

To all whom it may concern Be it known that I, WILLIAM R. Simona,

a citizen of the United States, and resident of Nashua, in theoounty of Hillsboroand State of New Hampshire, have invented new and useful Improvements in Machines for Winding Paper Tubes, of which the following. is a specification.

My invention relates to the art. of forming, tubes by winding a felted web, such as aweb of paper, in successive convolutions upon a cylindrical mandrel, and consists in improvements in machines for winding such tubes.

'1 he objects of these improvements are to increase the volume of output of a given machine, to produce tubes of high density, strength and regularity of form, and to reduce to a minimum the manual operations incidental to the handling of suclra machine and of the product.

Other and further objects and results peculiar 'to and associated with my improvements will transpire from the subjoined specifications which are addressed to that form of machine in which my improvements are displayed and embodied in the best manner known to me. I

My inventions and improvements are exemplified in the machine and its parts shown in the accompanying drawings, in which- Figure 1 is a front elevation of the front portion of the machine; Fig. 2 is a side ole *ation of \he -machine, sundry parts thereof being shown in diagram; Fig. 3 is a plan View, partly in section, of the mandrel frame and its adjustable bearings and sundry mechanical adjuncts thereto; Fig. 4 is a side elevation of one of the end standards of the machine and parts immediately associated therewith: Fig. 5 is in part a vertical elevation and in part a vertical section taken at. the line 5-45 of Fig. 1 showing one of the end standards and its mechanical adjuncts; Fig. 6 is a detail showing one of the .heads of the mandrel frame; Fig. 7 is a detail showing in section pprtions of the mandrel frame adjusting mechanism; Fig. 8 is a View in perspective and partly in section of the segmental suction roll which performs important functions in the machine;

and Fig. 9 is a vertical cross section of the suction roll and tube winding mandrel taken at the hue 9 9 of Fig. 1.

For the sake of: clearzicss in exposition, the several functionally related departments of this machine will be separately described; their interrelation will appear in the summary setting forth the operation of the machine as a whole.

- -Webf(n-m in (rout-hing, con imaging (and omtcwea'tranting menhtmism.-A web of paper is formed in the well known manner upon a rotating cylindrical mold indicated at A in Fig. 2. The mold cylinder A, and

the factors associated with it, constitutesv and represents the Web-former. This web is transferred to a web carrier B by the aid o'l a couch roll (7 which is heavily felted.

according to the usual and well known construction. considerable pressure upon the mold cylinder A so as to accomplish its web coaching function. The web carrier'B is a relatively thin, porous belt, preferably a felt, which intervenes between the couch roll C and the mold cylinder A but is so thin that it does not sensibly modify the action of-the couch roll C inthe performance of its function which is to remove the web of paper from the mold cylinder A. The web is thus transferred from the cylinder A to the web carrier B. This web carrier is an endless belt which passes from the couch roll C to and around the sectional suction roll D under the tube winding mandrel (presently to be described) and thence overa series ofrolls back to the mold cylinder and couch roll. This web carrier Bjsshown 111 Fig.

Tube winding mmidrcis (mo? manolrci -f7'ame.lhe iiie-ntli'el frame with its mark drels is shown in elevation in Fig 1. Each momi 'el E (of which there are four in the illusti'eticn shown) is jouinolctl at one encl to a pivot block E in the frame head E and at the other end inc, half socket E Where it is centered by e spring-controlled pin E (see Fig. 3). The mandrel frame heads E and E are secured to the frame shaft E which is journalccl at either end in a journal hoxl mounted to slicle for i vertical ad ustment on e standard R The adjustment of the mandrel. frame journal boxes (presently to be iceci'ihed more in detail) is such that each mandrel E when in the position shown in 1 beers heavily upon the Web carrier B, the bearing pressure being supported by the iiiiu and hard surface of the segmental LOll D. The yieldlug mountings of the mandrel frame, in the specific illustration represented by the drawings, constitute means to hohl the tube winding mandrel pressed'yieldingly against the Webdeliverer, in tubewincliiig position. The web. carrier B is so thin that the pres sure collect of e, mandrel E upon a Web of pope: carried by the carrier B is practically hel ces? i the same as though nothing intetw'ececl he- Ween the mandrel and the surface of. the segmental roll D lVitf a mandrel in this position and loeeing upon the web carrier,

The heed E of the menclrel frame shown at the right iii Fig. l is provided with peripheral notches these notches being; four in number to correspond with the uumher of menolrcls E, constituting stops which cooperate with detect, presently to he described. The periphery of the heecl E between. each two notches is not concentric with the shaft E hut descends tothe center from one notch to the next, so that each notch e is (leepei' at one side than at the other. A (letent G engages each of the uotchesc in succession in 2; men- 5181 presently to be described; for the present it sufiices to hey that when u tube of paper has etteinecl the desired. and pi-ecletei'minecl thickness upon e mandrel.

The movement-of the Web carrier B will in itself tonal to rotate the mondrelfreme in the direction imlicetetl hy the arrow in Fig. 2 this temiency however is supplemented h the mechanism shown in Fig. l and more in detail in 3,

At the left hand encl of the nmnclrei frame shaft E es viewecl in and 3, ii spur Wheel J is mounted to turn on the coil of the shaft 3E es 5; heerii leis J are sccut'erl to the shaft side of the hub of the "Wheelleis oi. Washers material are iii J and the hub J. Nuts J on the end of the shaft-E are used to adjust the hub J and collars J to a proper intimacy of on tact. The spur wheel J is cm'istantly-driven by a pinion H mounted on the shaft H and the latter is rotated constantly in the direction shown by the arrow in l ig, 2 through chain and sprocket connections actuated from the main shaft of the machine. The frictional contact between the hub J of the spur Wheel J and the washers 5 tends to rotate the shaft i l and time as soon. as the. mandrel frame is freed from restraint by the removal of the dcicnt G (Fig. 4:), the mandrel frame is rotated in the direction shown by the arrow in Fig. l.

The above described mechanism spm'ifically represents means to move a mandrel out of tubewinding position when, by the operation of disengageable holding devices, the mandrel is set free to be so moved. The operation of the releasing nicchanisn'i is momentary only and the detent G returns to position, so that riding on the eccentric periphery of the head E the detent G unfailingly engages the. mandrel frame head E by entering the next succeeding notch 6 arresting the rotation of the mandrel frame at the point where the bare mandrel comes into proper contact with the web carrier B.

Mamlrel frame detaining and releasing mechanism.-lhis' mechanism is shown in detail in Figs. 1 and 5 though reference may be made to Fig. 3. The detcnt (i' is secured to an arm of the detent plate (Jr. The dcl'cnt plate G is slotted at G so as to be guided in vertical movement upon the guide pins The de'lient late G is supported upon the spring G wlioh urges the plate upward so as normally to hold the detent G in contact with the mandrel frame head E and in engagement with, a notch 6 The detenhyicld mgly and therefore disengageably held in position against the head of the mandrel frame, in the specificillustration set forth in the drawings, represents and embodies. disengageable means to holda mandrel in tubewinding position. At the rear oi the delcnt plate (ii the trip, plate G is secured, this plate being adjustable vertically upon the detent plate G. In the upper portion of the trip plate G there is formed the housing G in which the trip G is pivotally mounted. A spring G holds the trip G" normally in the position shown in Figs. 4; and 5 and an adjusting screw G is provided whcrewith to make fine adjustments oi the trip 6.

The shaft i i jOlIllnRlQll in bearings l. is constantly rotated in the direction indicated by the arrow in Fig. 4. A, collar H secured to this shaft carricsa radially projecting finger H" which. nitrates immediately above a mandrel E and in the manner hereinabove indicated, it; hits the mandrel iramc by :torce of the growth of the tube itself on the man drel, the detent plate G, urged upward by the spring G followsthe mandrel frame, thus enabling the dctcnt G torctain its hold upon the mandrel framchcml l'), and this upward movement of the dctcnl plate (i continues until the end of the trip G is struck by the rotating linger H and is swun forward and downward carrying with it the dctcut plate G- 'and disengaging the detent G from the notch 0 '1hercupon, the mandrel frame rotating mechanism above described turns the nmndrel frame bringing the next mandrel into position. Before the nextmaudrcl reaches its position upon the web carrier 13, the rotating linger ll has leftits engagement with the trip ill", the spring G reasscrls itscli and lifts the dcicnt plate't and dctcnt G in time for the latter to catch the next notch c. The trip 6 in conjunction and coiiperation with the rotating trip-:wluator .ll. conslilulcs means to disengage the holding devices which hold a mandrel in tube-winding position, and these disengagingancans arc mediatcly controlled by the yielding movement of the tube winding mandrel, this movcmenl being in response to the growth of a tube wound on the mandrel.

The thickness oi -a paper tube to be wound will be determined by the adjustment of the trip plate (i supplemented by fine adjustmcntof the trip U itself. If the trip plate is raised and secured in raised position on the dclcnt plate G, then in the upward movement oil. the detent plate, the trip G will be the earlier brought into contact with the rotating linger ll, and the buildin up of a tube as 'l on the mandrel E (see Fig. 5) will be the sooner arrcslcd. To make a thicker tube, other things being the same, the trip plate G will l csccurod in a lower posilion on the dctcnt plate so that a longer lift is required to bring the trip G into contact with the finger ll".

As it is desirable to have a machine adapt ed to winding tubes of diil'crcnt diamclcrs,

that is to say, upon mandrels of different diameters, the entire system reprcsentcd by the detent plate (l and trip plale G and their adjuncts, is made vertically adjustable by being mounlcd upon a plate K on which are formed the bosses K in which the guide pins g are secured. The bracket K which serves as a scat for the spring G is secured to or integral with the plate K and the plate K is slotted as at K to admit holding bolts K by means of which the plate K. is secured at any desired position within the ran to of adjustment oil'ordcd by the slots K".

bus,

if the mandrel frame bc ccuippcd with pointto ei'n hle the fresh mandrel to form a tube in cooperation with the web carrier. As the paper tubes are brought to the front of the machine by the intermittent rotation.

of the mandrel frame, th tubular lnuntll'els are slipped 0d the mandi *1 cores, and fresh tubular mandrels substituted.

Incidentally/1 hav ,described my 'inventions and improvexu llts as applied to a paper tub'e winding machine of a type heretotore invented by me which forms the subject matter of an 'application tor patent filed Jan. i, 1911 by me serially numbered f 600,795. I prefer this type of machine for the reason that b its aid one is enabled to wind paper to yes of greater density, s rength mud regularity than upon tube winding machines heretofore in operation so for as t e same are known to me. This type of tube winding machine is one characterized by the employment of a relatively thin web-carrier which intervenes successively between a heavily felted couch roll and a mold cylinder ahd then between a tube winding: mandrel and a' firm,,hard supporting norface such as is attorded by the metallic scctional suction roll, and which is character ized also by the maintenance of water abstracting suction on the web carrier 11 to a point near to but short of the line 0 contact between the mandrel and the web carrier. The improvements hercinabove described and-hereinbelow claimed will, I believe, operate to best advantage when in- 85 corporabed with a machine of the general character just indicated; these improvements may, however, be found adaptable to tube winding machines of other types and may lend advantage thereto by reason of e0 their pntomatic character, complete adjustw bility and rapid operation.
